Post by: YAZID on Mar 19, 2018 A researcher conducts an experiment on a new drug for enhancing memory and the researcher concludes that the drug is effective. However, by chance alone the many participants having excellent memories were placed in the experimental group. This may lead to a:
a. Type I error. b. Type II error. c. correct rejection. d. correct acceptance. Question 2 If we retain the null hypothesis when it is true, we make a: a. Type I error. b. Type II error. c. correct rejection. d. correct acceptance. Question 3 If we reject the null hypothesis when it is true, we make a: a. Type I error. b. Type II error. c. correct rejection. d. correct acceptance. Question 4 The larger the F ratio: a. the less likely we are to reject the null hypothesis. b. the less likely our results are due to chance. c. the greater the probability of a Type I error. d. the less likely there is a confound.
